.SYNOPSIS...
Issued at 320 AM EST Sun Mar 7 2021

- Warming trend and mostly dry through mid week

- Wet toward the end of the week

&&

.DISCUSSION...(Today through next Saturday)
Issued at 320 AM EST Sun Mar 7 2021

-- Warming trend and mostly dry through mid week --

High pressure over Michigan will provide plenty of sunshine
today. Latest IR loop shows high clouds over the northern Plains
and some of these clouds will spill over into Michigan this
afternoon. We'll see quite a bit of sunshine today through
Tuesday, and as the ridge moves east, south flow will increase and
temperatures will rise each day through Tuesday. Tuesday will end
up being the warmest day and widespread 60 degree temperatures
will be found across the southern CWA and upper 50s across the
north. Clouds will be on the increase Tuesday night and Wednesday
as low pressure over the southern Plains moves northeast along a
frontal boundary.

-- Wet toward the end of the week --

As the Gulf opens up, moisture will stream north and interact
with several short waves moving through the southwest flow and
showers will develop, perhaps as early as late Tuesday, but more
than likely by Wednesday. Instability doesn't look high enough for
thunder at this point.

The best chance of rain looks to be late Wednesday night and
Thursday as the low moves by and drags a cold front through the
state. Confidence is pretty high that we'll see some rain during
this time, but how much is the question. The 00z model runs show a
little higher QPF across the southern CWA vs yesterday's runs,
but it doesn't last long as the front pushes south and takes the
rain with it. The main question is whether the front will hang up
over the southern part of the state or move south into Indiana.
Both the GFS and ECMWF push the frontal boundary south into
Indiana. In fact, the ECMWF pushes it south of the Ohio River. The
ECMWF ensemble mean is around 0.75 inches, which is similar to
both the GFS and Canadian ensembles. At this point, this doesn't
appear to be a flooding situation, but it's still several days
away and we'll keep watching it.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1120 PM EST Sat Mar 6 2021

Expect clear skies into Sunday afternoon. Winds will be light and
variable for the most part due to the surface high being over the
area. Sunday we will have the high moving off to the east but
winds will still be light and there could be a lake breeze west of
US-131 by late afternoon.

A warm front coming through the area will being some mid clouds
into the area Sunday night but no precipitation is expected from
these clouds.

&&

.MARINE...
Issued at 320 AM EST Sun Mar 7 2021

Winds will increase tonight as high pressure moves east. We'll
issue a Small Craft Advisory for tonight and Monday morning.

Stronger winds are expected Tuesday night through Wednesday night
and we may need a Gale Warning during that time.
